Searches for query terms inside of a file. This method returns up to 100 results per page.

When searching for code, you can get text match metadata for the file content and file path fields when you pass the text-match media type. For more details about how to receive highlighted search results, see Text match metadata.

For example, if you want to find the definition of the addClass function inside jQuery repository, your query would look something like this:

q=addClass+in:file+language:js+repo:jquery/jquery

This query searches for the keyword addClass within a file’s contents. The query limits the search to files where the language is JavaScript in the jquery/jquery repository.

Considerations for code search

Due to the complexity of searching code, there are a few restrictions on how searches are performed:

• Only the default branch is considered. In most cases, this will be the master branch.
• Only files smaller than 384 KB are searchable.
• You must always include at least one search term when searching source code. For example, searching for language:go is not valid, while amazing language:go is.

Find commits via various criteria on the default branch (usually master). This method returns up to 100 results per page.

When searching for commits, you can get text match metadata for the message field when you provide the text-match media type. For more details about how to receive highlighted search results, see Text match
metadata.

For example, if you want to find commits related to CSS in the octocat/Spoon-Knife repository. Your query would look something like this:

q=repo:octocat/Spoon-Knife+css

Find issues by state and keyword. This method returns up to 100 results per page.

When searching for issues, you can get text match metadata for the issue title, issue body, and issue comment body fields when you pass the text-match media type. For more details about how to receive highlighted
search results, see Text match metadata.

For example, if you want to find the oldest unresolved Python bugs on Windows. Your query might look something like this.

q=windows+label:bug+language:python+state:open&sort=created&order=asc

This query searches for the keyword windows, within any open issue that is labeled as bug. The search runs across repositories whose primary language is Python. The results are sorted by creation date in ascending order, which means the oldest issues appear first in the search results.

Note: For user-to-server GitHub App requests, you can’t retrieve a combination of issues and pull requests in a single query. Requests that don’t include the is:issue or is:pull-request qualifier will receive an HTTP 422 Unprocessable Entity response. To get results for both issues and pull requests, you must send separate queries for issues and pull requests. For more information about the is qualifier, see “Searching only issues or pull requests.”

Find labels in a repository with names or descriptions that match search keywords. Returns up to 100 results per page.

When searching for labels, you can get text match metadata for the label name and description fields when you pass the text-match media type. For more details about how to receive highlighted search results, see Text match metadata.

For example, if you want to find labels in the linguist repository that match bug, defect, or enhancement. Your query might look like this:

q=bug+defect+enhancement&repository_id=64778136

The labels that best match the query appear first in the search results.

Find repositories via various criteria. This method returns up to 100 results per page.

When searching for repositories, you can get text match metadata for the name and description fields when you pass the text-match media type. For more details about how to receive highlighted search results, see Text match metadata.

For example, if you want to search for popular Tetris repositories written in assembly code, your query might look like this:

q=tetris+language:assembly&sort=stars&order=desc

This query searches for repositories with the word tetris in the name, the description, or the README. The results are limited to repositories where the primary language is assembly. The results are sorted by stars in descending order, so that the most popular repositories appear first in the search results.

When you include the mercy preview header, you can also search for multiple topics by adding more topic: instances. For example, your query might look like this:

q=topic:ruby+topic:rails
